Question

a simple study of the people of an area revealed that total numbers of women were 40% and the percentage of coffee drinkers were 45 as a whole and the percentage of male coffee drinkers was 20. what was the percentage of female non-coffee drinkers?? A.10 B 15 C.18 D.208​

Answer 1

Let's assume the total population is 100.

Out of which 40% are women.

ie; 40 women & 60 men.

Given that, 45 %of the total population drink coffee.

20% of the population who drink coffee are Male.

so the percentage of the female coffee drinker (45-20) = 25%.

If females = 40% and 25% drinks coffee.

Then females who don't drink Coffee = (40%-25%) = 15.
